OIL-CAN.

Specification of Letters Patent.

Patented Nov. '12, 1907.

Application filed February 6. 1907- Serial No. 356,118

To all whom it may concern:

Be it known that I, SAMUEL R. PARKS, a citizen of the United States,residing at Pawtucket in the county of Providence and State of RhodeIsland have invented certain new and useful Improvements in Oil-Cans; ofwhich the following is a specification.

My invention relates to improvements in oil cans and the purpose of myinvention is to provide an oil can having a self cleaning plunger forthe purpose of removing obstructions from the nozzle and having also adevice for causing the bottom of the can to return to its normalcondition after pressure thereon has been removed. I accomplish theseobjects by the mechanism shown in the accompanying drawing showing acentral vertical sectional view of an oil can constructed in accordancewith my invention. and in which a represents the body proper of the oilcan, (1 its nozzle and a the orifice of the nozzle; a designates theflexible bottom of the can. Secured to this bottom is a metallic. strip0 of brass or steel or some other elastic metal; 0 is a similar metallicmember also secured to the bottom a e and c are ordinarily attached tothe bottom a by the rivets (l but may be secured in any other suitablemanner. The member e is curved upward at its free extremity and bearslightly on the under surface of the member a when the can is not in use.

Pivoted on c by an ordinary hinge joint I) is the plunger b, consistingof a met-allitrod of steel, brass or some comparatively rigid metal.Normally the plunger b reaches just to the orifice of a or remains atrifle within the same, but when pressure is exerted on the bottom (1through the agency of the members a and c the plunger 1) is projectedeven with or a little outside of the orifice a as shown by the dottedlines b-. The plunger thus operates to clear the orifice or nozzle fromany obstruction that may accidentally clog it. The plunger b is madeenough smaller than the orifice a to allow of a free flow of oil evenwhen I) is in the position shown by the dotted lines.

When the pressure is removed from the bottom a the latter is aided inits return to its normal position by the pressure of the two Springmembers 0 and 0. It

is a common defect of oil cans of the character disclosed to have thebottom 1& remain projecting upward after the pressure is removed so thatit becomes almost impossible even when the nozzle is clear to force theoil out of the nozzle, the only way in which this can be accomplishedbeing by unscrewing the nozzle altogether and introducing some tool intothe body of the can and pushing the bottom a downward to its normalposition. But by means of the members 0 and c the tendency to remainupward is entirely removed and the. bottom a is always in condition forthe forcing of the oil out through the nozzle by the application ofpressure on the bottom.

I am aware that prior to my invention oil cans have been in use andpatents have been granted therefor which embody a plunger operating inthe nozzle of the can. I am not aware however. that any such device hasbeen used in combination with the supplementary springs c-c for thepurpose of restoring the flexible bottom of the can to its normalposition on removal of the pressure thereirom.

I do not therefore broadly claim an oil can having a plunger adapted towork in the nozzle thereof for the purpose of freeing the same fromobstructions, but I What I do claim and desire to secure by LettersPatent is 1. In an oil can, a receptacle having a nozzle, a llat springmember secured adjacent one end to the inner face of the bottom of saidreceptacle and having its free end curved upwardly, a second springmember having one end secured to the inner face of the bottom of saidreceptacle adjacent the free cud ot' the first mentioned spring member.said second spring member being; curved to over-lie the free end of thefirst sprim, member and be engaged thereby. and a plunger rod extendinginto the nozzle and having its lower end pivoted to the free end of saidsecond spring member.

2. In an oil can. a receptacle having a nozzle. two leaf spring memberssecured to the inner face of the bottom of said receptacle, one of saidspring members over-lying the other spring member and engaging the freeend thereof, and a plunger rod extending into the nozzle and pivoted atits lower end to said over-lying spring member.

In testimony whereof I aflix my signature in presence of two witnesses.
